1. What are the names of the other two layers of the Earth, and what are they made of?

The two first layers of the erath are 1. the Crust 2. the Mantle

Explanation:

Crust is a solid layer of rock on the surface of the planet.

Mantle is a semi-liquid layer of magma or molten rock that moves due to cnvection currents.
